In the last year, the Swedish music platform Spotify has gained considerable media attention in the United States with their free online streaming service. Although many are hailing it as a great way of discovering new artists and music, many are also criticizing the site claiming that it fails to properly compensate independent artists.

Spotify offers a free service that can be accessed online, while access from a mobile device requires a paid “premium” membership. Furthermore, the paid membership allows you to bypass the video and audio advertisements that are present with the free account.

In 2010, Napster founder Sean Parker invested $15 million in Spotify’s development, and has since been involved by sitting on their board. Spotify cracked the ten million user mark that same year, with a quarter of the accounts belonging to paying customers. After many delays and years of negotiation with major record companies, the site finally launched its US version in July 2011.

Spotify compensates artists via their record labels by paying for both downloaded content and streaming. In some countries, record companies have marked a significant increase in revenue since joining Spotify. Not everyone is happy however, American rock duo The Black Keys have gone as far as pulling their newest album El Camino off the site. So why are so many speaking out against Spotify?
